You are not allowed to play more than two "pumping Bolts" in the same turn.
what's the point of this if the AI can't respect the rule (and we know that servers sucks, i got 3 desync in 5 battles, today)
Unless you play several cards like Pande or SoSe, desyncs are extremely rare. Keep in mind to never tab out during a game.
also i can understand that players like cardpool restrictions, but do in battle restrictions is too much.
I personally believe they provide something new. The first time I thought about alternative win conditions with "Nomination of the Queen", people liked it. A ruling like this is very similar, as in going around some of the technics of the game. However, I did not think about this restriction and then thought what ruleset to build around it, but I had the ruleset in mind and wondered how to balance it, which turned out to be quite difficult. The easiest way was to include this restriction, which also had the benefit of adding a bit more strategy to the games. With that being said, do you have another idea on how to balance this ruleset?
